was going to use a hardware wallet because i was planning to mine some bitcoin when my laptop was inactive. the program i downloaded said it has to transfer 150gb or so of data. i let it do its thing, but at the last second i changed my mind. i found that online solutions would be more efficient for me. i click cancel and the program exits. i even manually uninstalled the whole thing. afterwards though, 150gb of my 1tb hard drive was eaten up by the data i was never going to use. how do i delete it? i don't want it. i was using a program called bitcoin core wallet by the way.
